Your question is about Pistol BB guns, so I am not going to include rifles or Pellet guns. I'm also not including Airsoft.
First of all there is no BEST BB gun but there are quite a few choices of excellent BB guns. I like BB guns that have a good solid feel. These are usually made of Metal or Polymer plastic. I don't like plastic BB guns. I also like BB guns that have Blowback when they fire. I own over 30 different BB & pellet guns so I have a good Idea of the feel and differences in the models.
One of my favorites is the Walter PPK/s. It's not that expensive but it has a great feel. It is an exact copy of the real Walter PPK that was made famous by James Bond as his personal handgun. It has Blowback and cost around $60. (See the link below)
There are other excellent BB guns available but there is something you might want to know. BB guns are not as accurate as pellet guns and are only accurate up to 15 to 20 feet. Pellet guns are usually more accurate over a long distance.
I usually tell people the best BB gun is the one you can afford.

It's better known as a BB Gun. A BB gun is similar to a real firearm except it uses compressed air instead of gun powder.
It depends on the model
It can be either a BB gun or pellet gun. The slide, on top, blows back and reloads the next shot when you fire the pistol.

The suggested minimum age for owning a BB pistol gun is eighteen in the UK. There is no minimum age in America but people under fourteen need to be supervised by an adult.
The smallest BB is 4.5mm. As far as I know there is no 1mm BB gun.
